PLATFORM FOR WOOD-CHOPPERS.

SPECIFICATION formingpart of Letters Patent No. 500,527, dated June 27,1893.

Application filed April 27, 1892.

To all whom it may concern.-

Be it known that I, JOSEPH B. BRICKLEY, a citizen of the United States,residing at Port Angeles, in the county of Olallam and State ofWashington,haveinvented anew and useful Platform for Wood-Choppers, ofwhich the following is a specification.

My invention relates to improvements in devices for climbing trees, forthe purpose of cutting timber.

The objects of my invention are first to do away with the cutting ofholes in large trees, to enable a woodman to climb to a convenmm andadvantageous position when cutting timber. To more fully illustrate, thepresent custom on Puget Sound is to use what is known, as aspring-board, made of wood with a steel shoe, which is placed in thetree after a hole has been cut to receive it. In going up the necessaryheight to fall a large tree, it requires about eight holes, occupyingmuch time and labor to make, besides being attended with danger to theaxemen.

My invention will save both time and labor and be less dangerous. By useof it, one man can accomplish more than two in the same given time. Iattain these objects by the Serial No. 430,940. (No model.)

means illustrated in the accompanying drawings in which- Figure 1 is anelevation of my invention. Fig. 2 is a plan of the same.

A is the tree.

B is the spring board.

C is a circular iron bar on which B rests. D is also an iron bar, oneend of which is driven into the tree, the other is connected with thecircular bar 0, the upper hooks E, E and the lower hooks F, F, are alsodriven into the tree to brace and support the circular bar 0, and thespring board B, the thumb screw. G is a center around which the springboard is moved and by which it is fixed in any required position.

What-I claim as my invention, and desire to secure by Letters Patent,is-

The combination inaspringboard for wood choppers, of the standing boardB. the circular bar 0, and the driving bar D, with the hooks E, E and F,F, substantially as and for the purpose hereinbefore set forth.
